What is CVE-2025-15474?

The AuntyFey Smart Combination Lock firmware versions up to December 24, 2025, are susceptible to an exploit that enables an unauthenticated attacker within Bluetooth Low Energy (BLE) proximity to initiate an overwhelming number of BLE connection attempts. This barrage of connection requests can disrupt the lock's normal functionality, leading to repeated lockout states and blocking legitimate users from accessing the device via keypad authentication. As a result, the device remains inoperable for unintended periods, causing significant inconvenience and potential security risks for users.
